Architecture
Full composability, with self-contained business capabilities is the future of bank architecture. Three sub-trends will drive this: composability will follow an orchestration-led model, with banks running product factories, exposing domain capabilities to ecosystems, and reconfiguring architecture on demand. Cloud-native architecture will become event-driven, autonomous and self-optimizing, to power real-time banking, agentic AI adoption, and continuous digital innovation. As banks use event-sourced coexistence, automated strangler patterns and domain gateways to replace legacy capabilities slice by slice, modernization will become ongoing, business-led and low-risk.
